$ pdu path/to/file/or/directory
Compare disk usages of multiple files and/or directories
$ pdu file.txt dir/
Show chart in block sizes instead of apparent sizes
$ pdu --quantity=blksize
Show data in plain numbers instead of metric units
$ pdu --bytes-format=plain
Show data in base 2¹⁰ units (binary) instead of base 10³ units (metric)
$ pdu --bytes-format=binary
Show disk usage chart of all entries regardless of size
$ pdu --min-ratio=0
Only show disk usage chart of entries whose size is at least 5% of total
$ pdu --min-ratio=0.05
Show disk usage data as JSON instead of chart
$ pdu --min-ratio=0 --json-output | jq
Visualize existing JSON representation of disk usage data
$ pdu --min-ratio=0 < disk-usage.json
